Quantum Information Processing With Phonons

Abstract

The proposed program will explore phonons, and mechanical/acoustic vibration in general, as on-chip information carriers that can mediate interactions between spin qubits in diamond. The proposed program will explore phonons, and mechanical/ acoustic vibration in general, as on-chip information carriers that can mediate interactions between spin qubits in diamond. Our qubits will be centro-symmetric color centers in diamond, including silicon-vacancy (SiV), that feature strong spin-orbit coupling and large orbital response to applied strain fields. As a result, these systems feature a very large strain susceptibility and thus offer a unique opportunity to interface two or more qubits using coherent phonons. Different types of structures will be used to generate and localize acoustic modes, including surface acoustic waves, phononic bandgap materials, and optomechanical crystals.
